That's really interesting. As one of the co-authors I agree with your approach, but I also thought that so does the article. We put emphasis on following truth (as opposed to falling into nice illusions), being authentic, following your life mission (that's how I understand the "He who has a why to live for" part of your quote), and not escaping from sadness or problems. Even the heavily criticised inverted quotes mentioned "Happiness sometimes is being pained in body and troubled in mind". How come did you come to the conclusion that the article suggest avoiding pain and going for simple pleasures, easing up on the life's purpose? (Sorry for such a delayed response, a random life event cut in)
